In an era marked by the interconnected modern civilization, networks serve as the underpinning architecture that enables seamless information exchange across the globe. This chapter embarks on a journey through the realms of network from foundational concepts to visionary technologies. The chapter starts from switching methods, offering insights into how data traverses the network pathways. It delves into topologies that shape network resilience and performance. It extends the exploration to wired and wireless networks, unveiling industry standards and characteristics. In the domain of the Internet, the chapter explores its architecture, protocols, and hierarchical models, underscoring the significance of IP addresses and domain names. By inviting learners to consider factors that lead to slow network speeds or connectivity issues, the chapter engages learners in critical problem solving. Furthermore, by reflecting on the transformative potential of artificial intelligence (AI) and Internet of things (IoT) in their lives, learners explore the possibilities that the future holds. Whether improving network efficiency, embracing the IoT revolution, or contemplating the future, this chapter equips learners to navigate the landscape of global communication with confidence.
